How can I sample data from a database strata by date.

Table a, partitioned by date. I need to do a sampling of the table with more latest record and less older record and move it into a panda dataframe.

In The Joy of Clojure (TJoC) destructuring is described as a mini-language within Clojure. It's not essential to learn this mini-language; however, as the authors of TJoC point out, destructuring facilitates concise, elegant code.

Making Code More Understandable

One of the scariest things for those who are just now learning how to do some coding is the fact that they have to try to figure out what a seemingly impossible set of rules and structures means for the work that they are trying to do. It is not easy at all, and many people struggle with it in big ways. 

i am unable solve the error in my program

Hi guys, i am new here. Been on this code for some days and i seem stuck and not getting the expected output from this code.
first the code functions as a FIFO QUEUE where it takes input from the user and put it at the beginning of a list while deleting the last item on the list and creating a new list.
then i did function to search for four floating numbers (1.3,1.4,1.5,1.6) in the new list such that any float in the list that has identical integer part and decimal part split like any of the four floating numbers(1.4, 1.5, 1.6, 1.3) is denoted as a variant of the float e.g 17.34, 35.19 and 30.01 will be variants of float 1.3. Similarly 12.56, 57.17 and 10.50 will be variant of float 1.5. Also,a float like 14.31 if present in the list will be regarded as a variant of both 1.3 and 1.4 while float 15.61 will be regarded as a variant of both float 1.5 and 1.6.
So anytime the code runs, it takes the first THREE numbers each in the list or queue that are variants of 1.3,1.4,1.5 and 1.6 and create a new list for each variant. for example

list1 =[1.72, 10.60, 34.21,18.40, 11.13, 45.33, 1.03, 35.91]
this list has 4 variants of float 1.3
the new lists that will be created for float 1.3 from this list when i run the search function is:

new list a=[1.72, 10.60,34.21]

new list b=[1.72, 10.60, 34.21, 18.40,11.13]

new list c=[1.72, 10.60,34.21, 18.40, 11.13,45.33,1.03]

Lastly, the code performs a reverse indexing on each of the 3 new list with the second to the last number on each list having an index of 1 and third to the last digit having an index of 2. if there is any number in each of the new list that is equal to or greater than 2 with the same index index number, then there is a match. and the functions returns an output. the number only has to be equal to or greater than 2 but the index must match for all 3 new list.

from the above lists, the code returns an output like this" there is a match at index 1 for variant 1.3"

attached to this post is the code i have written. its a bit longer than it should if not i would have posted it on here. it runs without any problems for the first run, but subsequently fails to bring out expected output when i change the number in the list or when the queue FIFO starts working.

i will be happy if anyone can take a look and help check whats wrong with it or help modify it to work as i want

how to solve no 2 problem? i dont know how to do that, someone please help me :(

Hello
I create project based on c# , and i make roles like admin and users , so that i want to give special premission to users to perfom tasks .

if anyone know how i can make or write this code , please help me .

and in advance THANKYOU.

Write a function that takes a number and returns an array of
its digits. So, for 2342 it should return 2,3,4,2

Need help, been stuck on this the past couple days i dont really understand how to get my code to read from my file and count each occurence of a letter wheter they are uppr or lower case and output them to a file, just need help with the counting part, have to do it all through a function.

Here is my source code:

#include <iostream>
#include <fstream>
#include <iomanip>
using namespace std;
void getData(ifstream& inPara, ofstream& outChara, char texT[], int numLet[]);

int main()
{
    ifstream inFile;
    ofstream outFile;
    char ch[26] = {'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'};
    int numofCharacters[26] = {0};
    char target;

    inFile.open("Lab7.txt");//opens input file

    if (!inFile)//runs error if inFile could not be opened
    {
        cout << "Error unable to open Input File" << endl;
        cout << "Program Terminated!" << endl;
        return 1;
    }

    outFile.open("Output.txt");//opens Output File

    if (!outFile)//runs error if Output File could not be opened
    {
        cout << "Error unable to open Output File" << endl;
        cout << "Program Terminated!" << endl;
        return 1;
    }
    while (!inFile.eof())//runs program untile end of file
    {
        inFile >> target
    }

    inFile.close();
    outFile.close();

    return 0;
}

void getData(ifstream& inPara, ofstream& outChara, char texT[], int numLet[])
{

    for (int i = 0; i < 26; i++) {
    if (texT[i]) {
        numLet[i]++;
        }
    }
    for (int i = 0; i < 26; i++) {
        cout << numLet[i] << " " << endl;
    }
}

I want to pick whats best starting out that will help me move to better language in the future. Preferably something to benefit me in employment/University. Im not the quickest of learners. Thank you

First, it has been a LONG time since Ive been here. Good memories from when I was young.

Anyways

In a monitoring system I have, I had a plugin that remotely checked a SMB share and if the file hasnt been modified in 1 day, it should return a warning. if it is 2 days or more, it should return a critical.

Returning the warning and the critical isnt the issue, its the entire logic of the script itself.

I mean, I dont think it should be too difficult but Im not used to shell scripting. Also, the downfall exists, of having to check if the mount is correct, etc.

The logic is basically

inputvariable warningdays
inputvariable criticaldays
inputvariable smbpath
mount smbpath to final folder /mnt/folder
if mount is unsuccessful
return unknown
if mount is successful
if /mnt/folder/file does not exist
return unknown
if /mnt/folder/file does exist
if /mnt/folder/file has been written to less than warningdays
return ok
if /mnt/folder/file has been written to more than warningdays and less than criticaldays
return warning
if /mnt/folder/file has been written to more than criticaldays
return critical
if previousoperations are done
unmount
if unmount is unsuccessful
return unknown
finish

Could someone tell me the basics of the shell script?

Thank you.
